1?

anonymous · Answer

i dont really get the question

ajprincess · Answer

to solve for m, u have to isolate m. as u can see 5 has been subtracted from 4m. in order to remove it u have to add 5. if u add 5 to one side u have to add 5 to other side too. this wil give u
4m-5+5>-9+5
4m>-4
Bt still m is nt alone. 4 has been ,multiplied to it. to make m alone u have to divide by 4. if u divide by 4 one side u have to divide by 4 the other side too. this will give u
4m/4>-4/4
m>-1
